100% my favorite version too. By far. I liked the character a lot more back then, partly because the model actually looked natural instead of the aberration currently in the game.
I think it's the other way around. "Fatness", as far as I know, is determined by one's BMI which indicates the amount of body fat according to age, height and weight.
The curious thing about BMI is that skinny-looking people can actually be "fat" but no fat-looking person is ever gonna be considered "lean" by BMI standards unless they are ripped. I don't think the love handles on Mila's body are made up of muscle, bud...sorry to burst that bubble
I get what you're trying to say, that that particular distribution of fatty tissue is attractive to you. You do you, there is nothing wrong with that. But the fact that she is by any scientific standards, fat, is factual. Regardless of what your eyes or personal taste may say
